1. Who can use mLegitymacja?

mLegitymacja can be ordered by a student who meets all the following criteria:

  • has an active student status;
  • has a PESEL number;
  • has an student album number;
  • has a photo in the USOS system;
  • has an Electronic Student Identification Card (plastic);
  • Electronic Student Identification Card (plastic) has been renewed in USOS;
  • the student’s personal data has not changed since the Electronic Student Card was issued.

It is worth noting that it is the student who decides if and when he/she will install mLegitymacja, as he/she goes through all the steps on his/her own without interference of the university administration.

2. How to activate my mLegitymacja?

Every BUT student has the possibility to activate the card. To do so, there are 3 steps to follow:

3. mLegitymacja in the USOSweb

  • Log in to your USOS web account USOSweb
  • Go to the „Student’s section” tab (top menu of the panel);
  • In the side menu, select mLegitymacja in My studies (1);

  • After a few minutes, you should refresh the USOSweb page. If the mLegitimation is ready to download, a page with the QR code (4) should appear and activation code (5). The next steps to activate mLegitimacy will be done in the mCitizen application.

5. How to activate your mLegitymacja?

  • Download and install the mObywatel application and then log in.
  • In the „My studies” panel, click on „mLegitymacja”.
  • Go through the activation steps and read the terms and conditions (optionally, you can allow the app to use the camera to enter information; by default, you can type them).
  • Scan the QR code and confirm with the activation code – both codes can be found in USOSweb or in Mobile USOS PB under mLegitymacja (4) – then click on „Activate”.
  • Once you have completed the above steps, you can start using your mLegitymacja.


  • Every time you renew your ELS, you must extend the validity of your mLegitymacja or, if you are resuming your studies, order your mLegitymacja anew.
  • The student may cancel mLegitymacja at any time. Such a request is transmitted to the mObywatel system immediately, but mLegitymacja may remain valid for a certain period of time (not longer than 24h).
